A theoretical and empirical examination of wage differentials findsthat traditional theories of competition do not explain why workers with identical skills are paid differently.

Known for his seminal work in efficiency-wage theory, Andrew Weiss surveys recent research in the field and presents new results. He shows how wage schedules affect the kinds of workers a firm employs and how well those workers perform on the job. Using straightforward examples, he demonstrates how efficiency-wage theory can explain labor market outcomes and guide government policy. There is a separate section of applications to less developed countries. "Efficiency-wage models represent one of the most important developments in economic theory of recent years. They have, at last, provided integrated explanations both of macroeconomic phenomena, such as unemployment and wage rigidity, and microeconomic phenomena, such as wage dispersion. Weiss--one of the pioneers of efficiency-wage theory--provides here a masterful survey, a lucid and systematic and yet critical account of this rapidly developing branch of economics. This book should be required reading in all courses in macroeconomics."--Joseph Stiglitz, Stanford University "Efficiency Wages should be on the bookshelf of all labor and macroeconomists."--Lawrence H. Summers, Harvard University "A splendid monograph ... most readable... I will put it on my reading list."--Partha Dasgupta, Stanford University Originally published in 1991. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.

The distribution of income, the rate of pay raises, and the mobility of employees is crucial to understanding labor economics. Although research abounds on the distribution of wages across individuals in the economy, wage differentials within firms remain a mystery to economists. The first effort to examine linked employer-employee data across countries, The Structure of Wages:An International Comparison analyzes labor trends and their institutional background in the United States and eight European countries. A distinguished team of contributors reveal how a rising wage variance rewards star employees at a higher rate than ever before, how talent becomes concentrated in a few firms over time, and how outside market conditions affect wages in the twenty-first century. From a comparative perspective that examines wage and income differences within and between countries such as Denmark, Italy, and the Netherlands, this volume will be required reading for economists and those working in industrial organization.

The contributors explore the reasons why involuntary unemployment happens when supply equals demand.

Designing a good unemployment insurance scheme is a delicate matter. In a system with no or little insurance, households may be subject to a high income risk, whereas excessively generous unemployment insurance systems are known to lead to high unemployment rates and are costly both from a fiscal perspective and for society as a whole. Andreas Pollak investigates what an optimal unemployment insurance system would look like, i.e. a system that constitutes the best possible compromise between income security and incentives to work. Using theoretical economic models and complex numerical simulations, he studies the effects of benefit levels and payment durations on unemployment and welfare. As the models allow for considerable heterogeneity of households, including a history-dependent labor productivity, it is possible to analyze how certain policies affect individuals in a specific age, wealth or skill group. The most important aspect of an unemployment insurance system turns out to be the benefits paid to the long-term unemployed. If this parameter is chosen too high, a large number of households may get caught in a long spell of unemployment with little chance of finding work again. Based on the predictions in these models, the so-called "Hartz IV" labor market reform recently adopted in Germany should have highly favorable effects on the unemployment rates and welfare in the long run.

This volume seeks to go beyond the microeconomic view of wages as a cost having negative consequences on a given firm, to consider the positive macroeconomic dynamics associated with wages as a major component of aggregate demand.
